- /* Normally, this uses ((xword - 0x01010101) & 0x80808080) test
- to find out if any byte in xword could be zero. This is fast, but
- also gives false alarm for any byte in range 0x81-0xff. It does
- not matter for correctness, as if this test tells us there could
- be some zero byte, we check it byte by byte, but if bytes with
- high bits set are common in the strings, then this will give poor
- performance. You can #define EIGHTBIT_NOT_RARE and the algorithm
- will use one tick slower, but more precise test
- ((xword - 0x01010101) & (~xword) & 0x80808080),
- which does not give any false alarms (but if some bits are set,
- one cannot assume from it which bytes are zero and which are not).
- It is yet to be measured, what is the correct default for glibc
- in these days for an average user.
